O'Malley argues for assault weapons ban on MSNBC

Gov. Martin O'Malley took his call for a ban on assault weapons to national television Wednesday night, arguing on MSNBC's Hard Ball that "these combat weapons have no place in a civilized society."

O'Malley this week said his administration is crafting a package of state gun-control legislation likely to be introduced during the General Assembly session that begins next month. Wednesday night, O'Malley told MSNBC's Chris Matthews that political sentiment has shifted.

"I think we've all been changed as a country," O'Malley said in a segment that included former Pennsylvania governor Ed Rendell, who also encouraged stricter gun laws in the wake of the Connecticut shooting that killed 27 people, 20 of them elementary school children.
